Have no idea unless details of the investigation come out before the trial begins but it will get tricky if indeed the Tsarnaev brothers can be tied to the same groups of Chechen jihadists knowing that FSB Director Bortnikov mentioned in the same memo, was evidenced this past week by Ahmed al-Ibrahim, an adviser to some of Saudi Arabia's royals and officials, who stated: “The bond of trust between America and Saudi Arabia has been broken in the Obama years, we feel we have been stabbed in the back by Obama.” Although the post came after the Boston Marathon attack it doesn't look good.
